Sydney is one of the best-placed cities in Australia for solar, with strong year-round sunshine and government incentives that bring the upfront cost down. Once rebates are applied, a quality system is more affordable than many homeowners expect. This guide covers what solar costs in Sydney right now, the incentives that lower the price, and how to choose an installer without overpaying or cutting corners.
How much do solar panels cost in Sydney?
Prices vary with system size, the panels and inverter you choose, and how complex your roof is. As a guide, here are typical installed ranges for Sydney after the upfront STC discount is applied.
| System size | Typical installed price (after STC discount) | Suits |
|---|---|---|
| 6.6kW | ~$4,000 to $7,000 | Average homes |
| 10kW | ~$7,000 to $11,000 | Larger homes, higher usage |
| 13.2kW | ~$9,000 to $13,000 | Big households, small business |
Larger systems usually cost less per kilowatt, so stepping up in size is often better value than it first looks. The best way to know your real figure is a quote based on your roof and usage. You can browse the solar panels we install and check our current offers for the latest pricing.
Government incentives that lower the cost
The main saving comes through the federal Small-scale Renewable Energy Scheme (SRES). Your system earns Small-scale Technology Certificates (STCs), which your installer claims and applies as an upfront discount, so you pay the reduced price rather than claiming anything back yourself.
Sydney sits in STC Zone 3, one of the higher-yielding zones, so systems here earn a solid number of certificates. One thing to know: the scheme is winding down to 2030, and the number of certificates a system earns drops a little each year. In practice that means the discount is slightly smaller every year you wait, which is worth factoring into your timing.
If you are adding battery storage, the federal Cheaper Home Batteries Program provides a separate discount on eligible batteries. You can read the current details on our federal battery rebate page.
Feed-in tariffs, the credit you get for exporting surplus solar to the grid, still exist but have fallen across NSW in recent years. That means the bigger saving now comes from using your own solar during the day rather than exporting it, which is part of why batteries have become so popular.
What affects the price of a solar system?
Two quotes for the same size system can differ by thousands. The main factors are:
- Panel and inverter quality: premium components cost more upfront but last longer and produce more, which usually pays off over the system’s life.
- System size: bigger arrays cost more in total but less per kilowatt.
- Roof complexity: steep, tiled or multi-storey roofs take longer to install than a simple single-storey job.
- Electrical work: switchboard upgrades or single-to-three-phase changes add to the cost.
Component quality is where cheap systems cut corners. A better panel and inverter combination protects your solar panel efficiency and output for the long run, so the cheapest quote is rarely the best value.
How to get an affordable system without cutting corners
- Get a few quotes: compare price, equipment and inclusions from two or three reputable installers rather than taking the first offer.
- Check accreditation: make sure the installer is accredited by Solar Accreditation Australia and uses Clean Energy Council approved products, which is also required to qualify for the rebate.
- Be wary of very cheap deals: unusually low prices often mean budget components or rushed installation that costs more later.
- Look at the warranty: strong product and workmanship warranties are a sign the installer stands behind the job.
Spreading the cost with finance
If the upfront price is a barrier, finance lets you pay the system off over time, often with the bill savings helping to cover the repayments. We offer flexible finance options so you can start saving without a large outlay on day one.
Is solar worth it in Sydney?
For most Sydney homes, yes. After the upfront rebate, a well-sized system typically pays for itself within a few years through lower power bills, then keeps saving for the rest of its 25-year-plus life. Solar can also lift your property’s value, since buyers see an installed system as a cost they no longer have to fund themselves.
Frequently asked questions
How much do solar panels cost in Sydney?
As a guide, a 6.6kW system runs about $4,000 to $7,000 installed after the STC discount, a 10kW system about $7,000 to $11,000, and a 13.2kW system about $9,000 to $13,000. Your exact price depends on your roof, usage and chosen equipment.
What rebates are available for solar in Sydney?
The federal SRES provides Small-scale Technology Certificates that your installer applies as an upfront discount. If you add a battery, the Cheaper Home Batteries Program offers a separate discount. Feed-in tariffs also credit you for exported solar, though these have fallen in NSW.
Is solar worth it in Sydney?
For most homes, yes. After rebates, a well-sized system usually pays for itself within a few years and keeps saving for decades, while also adding to property value.
How can I make solar more affordable?
Get multiple quotes, take full advantage of the rebate, choose a sensible system size, and consider finance to spread the cost so bill savings help cover repayments.
Does waiting cost me more?
Slightly. The number of certificates a system earns under the SRES drops a little each year as the scheme winds down to 2030, so the upfront discount reduces over time.
